我真的想知道为什么我的字符串替换过程在解析包含任何特殊字符(包括感叹号)的文本文件时起作用.我预计延迟变量扩展会关闭&符号,百分号等的特殊含义,但会因感叹号而失败…
@H_404_40@码：
@echo on & setlocal ENABLEEXTENSIONS
set "InFile=%~1"
set "OutFile=%~2"
set "Replace=%~3"
CALL :ParseCue "%%InFile%%" "%%OutFile%%" "%%Replace%%"
endlocal &GOTO:EOF
:ParseCue
@echo on & setlocal ENABLEEXTENSIONS DISABLEDELAYEDEXPANSION
set "FileToParse=%~1"
set "OutputFile=%~2"
set "NewExtension=%~3"
for /F "usebackq tokens=* delims=" %%a in ("%FileToParse%") DO (
set "line=%%a"
@echo on & setlocal ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
set "line=!line:.wav=%NewExtension%!"
echo(!line!>>"%OutputFile%"
endlocal
)
endlocal &GOTO:EOF
InputFile.txt：
This a test for parsing lines with special characters
Rock & Roll.wav
Rock & Roll!.wav
Special | < > ~ \ ²³ { [ ] } ! " ´ ' ` üäö @ ; : € $% & / ( ) = ? chars.wav
命令行语法：
D:\Users\Public\Batch\YAET>parse.bat "InputFile.txt" "OutputFile.txt" ".flac"
OutputFile.txt：
This a test for parsing lines with special characters
Rock & Roll.flac
Rock & Roll!.flac
Special | < > ~ \ ²³ { [ ] } ! " ´ ' ` üäö @ ; : € $% & / ( ) = ? chars.flac
编辑/补充：
1年半后,我不得不再次使用此代码段.请参阅另外两个处理毒性字符的示例.第一个是暂时启用延迟扩展(请参阅Ansgars答案),第二个使用CALL.两者都将解析当前目录中和下面的非空文件的路径和名称,但不会跟踪驱动器号和当前目录的路径.
示例#1(在“File =！File …”集合中包含双引号,并且不需要echo“！FILE！”>> …)：
@echo off & setlocal ENABLEEXTENSIONS DISABLEDELAYEDEXPANSION
del NonEmptyFiles.txt >NUL 2>&1
echo Searching non-empty files in and below current directory ...
for /f "tokens=*" %%I in ('dir /s /b /a:-D') do (
if not %%~zI==0 (
set "File=%%I"
setlocal ENABLEDELAYEDEXPANSION
set "File=!File:%cd%\=!"
echo "!File!">> NonEmptyFiles.txt
endlocal
)
)
echo Done. See NonEmptyFiles.txt.
endlocal &goto:EOF
示例#2(较慢,需要包含双引号)：
@echo off & setlocal ENABLEEXTENSIONS DISABLEDELAYEDEXPANSION
del NonEmptyFiles.txt >NUL 2>&1
echo Searching non-empty files in and below current directory ...
for /f "tokens=*" %%i in ('dir /s /b /a:-D') do (
if not %%~zi==0 (
set "File=%%i"
call set "File=%%File:%cd%\=%%"
call echo "%%File%%">> NonEmptyFiles.txt
)
)
echo Done. See NonEmptyFiles.txt.
endlocal &goto:EOF
